Buffalo Bills safety Aaron Williams went through a series of tests on his neck and head area and was released from a hospital Sunday.

Williams was hurt after diving to make a tackle in a 40-32 loss to New England, landing his helmet on receiver Julian Edelman's back and having his head bounce off the turf.

Coach Rex Ryan said Williams was taken to the hospital for what he called a ''cervical precaution,'' then the team announced Williams was released from the hospital.
